Mixing and non-premixed combustion at supercritical pressures

, 2017
This thesis is devoted to the numerical investigation of mixing and non- premixed combustion of cryogenic propellants at supercritical pressures. These severe conditions are commonly encountered in high pressure combustion chambers, such as those of liquid-fueled rocket engines (LRE), and lead to significant deviations from the ideal gas thermodynamic ...

Modelling of turbulent swirling flows [PDF]

, 2004
This thesis investigates the predictability of non-reacting and reacting anistropic turbulent, swirling flows using popular turbulence models with a robust numrical procedure. The performance of these turbulence models is assessed and compared against

Characterization of carbonaceous nanoparticle size distributions (1-10 nm) emitted from laboratory flames, diesel engines and gas appliances

, 2008
Commercially available SMPS and a differential mobility analyser (DMA) designed to enable detection of particles as small as 1 nm were used to provide further information about nanoparticles emitted from premixed flames, engines and common burners, with ...

Determination of the effectiveness of a Hot Tube igniter for initiating HCCI combustion

, 2006
Includes bibliographical references (leaves 61-63).Homogeneous Charge Compression Ignition (HCCI) is a new internal combustion system that promises high efficiency and dramatically reduced nitrous oxide (NOJ and particulate matter (PM) emissions when ...

Simulations of edge-flame propagation in turbulent non-premixed jets

, 2007
Ignition, flame propagation and stabilisation have been simulated and analysed in a turbulent jet of non-premixed methane and air. The first order Conditional Moment Closure (CMC) turbulent combustion model was fully coupled with a Reynolds-Averaged ...

Filtered density functions from direct numerical simulation of a reactive jet in cross-flow

, 2010
Direct numerical simulation (DNS) with multi-step hydrogen-air chemical kinetics is used to investigate the nearfield of a flame stabilized above a reactive jet in cross-flow (JICF). JICF configurations are typically used where rapid mixing is desirable;
